Answer:

Step-by-step explanation:

27 + D + 2A + C = 25 + D + B + C + A

subtract D, A, C on both sides

=> 27 + A = 25 + B

=> B = A + 2

3D + A + 29 = 2B + D + A + 27

=> 2D + 29 = 2B + 27

=> 2D = 2B + 27 - 29

=> D = B - 1

substitute:

27 + (B - 1) + 2(A + 2) + A = 2A + B + 30

substitute again:

2A + (A + 2) + 30 = 3A + 32
